This invention relates to an unloading apparatus and more particularly to an appa ratus adapted to be mounted in a barn and by means of which hay may be unloaded b from a hay wagon and deposited in a hay mow.

One object of the invention is to provide an apparatus of this character including a carriage movable along an overhead track and having improved means for imparting movement to the carriage along a track from a position over a hay wagon to a pos1- tion above the hay mow.

Another object of the invention is to pro- A vide an apparatus of this character including a tow rope for the carriage intended to be drawn by draft animals and engaged about a drum to be rotated'as the rope moves. 7

Another object of the invention is to insure rotation of the drum as the rope moves and further yieldably resist rotation of the drum as the rope is drawn upon to move the carriage'over the hay mow thereby asi sisting return movement of the carriage to a position over the hay wagon.

Another object of the invention is to cause a rope carrying a weight to effect reverse rotation of the drum to be wound upon the 3 drum shaft as the carriage is moved along the track.

The invention is illustrated in the accompanying drawings wherein Figure 1 is a diagrammatic perspective A View of the unloading apparatus.

Figure 2 is a similar view showing the carriage moved to a position over a hay mounted in a barn.

Figure 4 is an enlarged view illustrating the drum and mounting means therefor.

This improved hay unloading apparatus is intended to be erected in a barn or similar from the'fork andthe hay willjdrop into building 1 in which hay is to be stored and includes an overhead track 2 mounted in the barn in such position thata carriage 3 may travel alongthe track from a position over ahay wagon driven into the barn to "a posi- 5. tion over a hay mow anda load of hay, 4 V 'carriedby a fork 5 dropped. The fork "5 is of a conventional construction. andbar the usual trip rope 6' so that afterfit has been movedupwardly from the loading p0sition shown in Figure 1 and engaged'withthe carriage for transportation to a position 'over the hay mow the load may be released and allowed to drop from the fork."

' The tow rope 7 which is attached at'one endto the carriage 'asshown at 8and engaged with pulley wheels 9 of the'carriage has a depending looped portion 10 engaged with the pulley wheel'll so that the carriage maybe lowered to a loading position" and 7 drawn upwardly into position to engagethe carriage when pull is exerted upon the rope. The rope extends longitudinally of the track 2 and after being'wrapped about the drum 12 is engaged'with a pulley 13 s'ecured to the barn and then extended downwardly and engaged about a pulley 14. Adraftappliance 15 is secured to the rope 7 i and when draft animals hitched to the draft appliance exertpull upon the rope the fork'will be drawn upwardly to the carriage and the a fork and carriage then'nioved alongthe track I to a position over the hay mow. The trip rope can then be pulled to release the hay the mow; I p H V y The drum 12 is fast upon a shaft 16 rotatably mounted in bearing brackets 17 carried by the barn and at one side of thedrum is 9 disposed a sleeve or spool '18 which rotates with the drum and shaft and has ahead 19 shown in Figure 6 so that rotation of the drum and spool willbe assured when the rope 7 is drawn upon to raiseithe forkyandeh move the carriage along the track to a position above the hay mow. v

I In order to assist rotation of the drum in a reverse direction there is provided a weight 21 having a pulley wheel 22 engaged by the depending looped portion of a rope 23. This rope has one end portion wrapped about the spool and secured to the head 19 as shown at 24 and is engaged with the pulley wheel 25 and then extended downwardly and upwardly to form the loopengaging the pulley wheel 22 and secured to the mounting brackets 26 for the pulley wheel 25 as shownat 27 in Figures 1 and 7. By this arrangement the rope 23 will be Wound upon the spool 18 as the carriage is .moved towards the dumping position, and the weight lifted. After the hay has been dropped the draft animals are ,driven towards the barn and as the rope 7 is slackened pull of the weight will rotate the spool and drum in a reverse directionfand reel the rope 7 inwardly so that the carriage may be easily returned to the loading position overthe hay wagon by a pull rope (not shown) or any other clesiredmeans and the fork drop to the lowieredposition shown in Figure 1. i

I From the foregoing description of the construction of my improved apparatus the operation thereof and the methodof applying the same to use will be readily understood.

It will be seen that Ihave provided a simple,

inexpensive and efficient means for carrying out the objects of the invention and while ;I have particularly described the elements .ing longitudinally of said track and having one end secured to the carriage and ;a portion extending downwardly from the carriage and trained about a pulley'wheel carried by the grapple whereby movement of the grapple towards andaway from the'carriage may be controlled, hangers at opposite sides of said track adjacent one end thereof, a shaft-rotatably supported by said hangers between the drum and rope and cause the drum to rotate when the rope is drawn upon, and means to yieldably resist rotation of thedruin and shaft in one direction consisting of a cable having one end wound upon said shaftand its intermediate portion engaged with a guide ulley, said cable extending downwardly rom the guide pulley and then upwardly and secured toform 2; depending loop, and a weight having suspending pulley engaged "with the depending looped portion of the'cable to exert pull uponthe cable and resist rotation of the shaft and drum in one direction.

In testimony whereof I'aflix my signature.
